I have an inground pool in Miami, FL, water table I think is 3 to 4 feet
below grade, the pool is 7 feet deep.

I was told that if I drain the pool it would crack.

However, I need to get it replastered, and now, I am doing major renovation
on the house, and will not be using the pool for another 4 months. I would
prefer to not have to buy chlorine, shock, acid, PH, and run the pump and
filter for 8 hours a day for no reason for 4 months.

Can I drain the pool and leave it dry in the mean time?

I think there is a valve at the bottom of the pool for pressure release, but
I am not sure...

Thanks in advance,

MC
